Question about Panasonic PT-47WX53 47" Rear Projection HDTV
Hello again guys and gals.
Well here I am again with the same problem as I had before. convergence. blue gun still of the charts. replaced the convergence amps. Both. still nothing. I did read something on the back of the tv about the eprom? what is it and could that be my problem? If not what other solutions am I looking at? anyone?
still banging my head against the wall,
Convergence amps require B+ voltage to run them...they originate in the power supply and are fuse protected......then
they are fed to current limiting resistors near the IC's....
These devices must be checked......But,the #1 problem is use
of less than first quality IC's......STK392-110's,-120 and-150 can
be upgraded to STK394-160E made by Sanyo.....I use Hitachi
part # CZ 01341 or save money = buy kit with two IC's and some resistors part # X 480293...........read any of my convergence
